Synopsis
=======
gFTP is vulnerable to directory traversal attacks, possibly leading to
the creation or overwriting of arbitrary files.

Background
=========
gFTP is a GNOME based, multi-threaded file transfer client.

Affected packages
================
    -------------------------------------------------------------------
     Package       /   Vulnerable   /                       Unaffected
    -------------------------------------------------------------------
  1  net-ftp/gftp      < 2.0.18-r1                        >= 2.0.18-r1

Description
==========
gFTP lacks input validation of filenames received by remote servers.

Impact
=====
An attacker could entice a user to connect to a malicious FTP server
and conduct a directory traversal attack by making use of specially
crafted filenames. This could lead to arbitrary files being created or
overwritten.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All gFTP users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/gftp-2.0.18-r1"
